○ Topic: A theory of Non-Fermi liquid by Holography
○ Speaker: 신 상 진 교수님 (한양대학교)
○ Date/time: 2023. 6. 22. (Thu.) 4:00 PM
○ Place: Natural Science 1, Room No.31317
○ Abstract: We study the singularity structure of the one particle Green functions by Holographic method at and near the quantum critical point.
At the critical point, the spectral function shows a characteristic behavior of nonFermi Liquid coming from the branch cut singularity.
Under the presence of the symmetry breaking with a particular tensorial order parameter, the fermion spectral function shows different transition.
Most of them remains in non-Fermi liquid but some of them shows the quasi particle induced by the order.
